[Mageia-dev] unable to create kernel and grub files when using unsquashfs (before moving to /usr it used to install ok)

Sun Jul 29 06:55:18 CEST 2012

Hi,
+
+Problems installing grub files and kernel files under /boot since i
+have followed the Coling instructions about moving to /usr, but i dont
+know if these problems are related to this or due to other changes in
+systemd.
+
+Since linuxmint doesnt have an installed to install the distro in an
+encrypted LVM i have followed this howto
+http://forums.linuxmint.com/viewtopic.php?f=141&t=71159  and i have
+put linuxmint in an encrypted LVM and so far all went fine.
+
+Some days ago i decided to replace Linuxmint by Ubuntu and i did
+followed the same procedure and again all was running fine.
+
+However today i have decided to replace Ubuntu 12.04  with Ubuntu
+12.10 (quantal) and i have erased existent Ubuntu fs and i followed
+the same procedure, but after running:
+
+ubuntu]# unsquashfs -f -d /mnt/lm/ casper/filesystem.squashfs
+Parallel unsquashfs: Using 4 processors

+
+it did NOT install vmlinux ubuntu kernel file in /boot like it used to
+happen so far, and it also did not installed the grub files that used
+to install and isntead now i have this:
+
+boot]# ls -ls *
+ 824 -rw-r--r-- 1 root root  843468 Jul 23 21:15 abi-3.5.0-6-generic
+ 148 -rw-r--r-- 1 root root  147800 Jul 23 21:15 config-3.5.0-6-generic

+
+grub:
+total 4
+4 -rw-r--r-- 1 root root 699 Jul 24 13:04 gfxblacklist.txt
+
+as we can see theres no grub files inside /boot/grub and also theres
+no initrd and vmlinux files to allow to boot into Ubuntu.
+
+I even tested by installing again the Ubuntu release that was
+successfully installed (before following Coling instructions about
+moving to /usr) and now it happened exactly the same thing, no
+vmlinux, initrc and no grub files.
+
+
+Could anyone please clarify, or Colin ;) why now when running
+"unsquashfs -f -d /mnt/lm/ casper/filesystem.squashfs" it doesnt
+install kernel and grub files needed to boot the distro?
+
+
+PS: i need to use this procedure even with Ubuntu since i want to have
+in an encrypted LVM with cypher aes-xts*  because Ubuntu alternate CD
+installer uses an older cypher.
+        for linuxmint i really have no other option that use this
+since it doesnt have an installer that allows to install the distro in
+an encrypted partition (it only allow to encrypt home folder)
+
+TIA
+
+regards,
+Pedro
